It requires a simple interface for in-system programming. On-chip address and data latches, self-timed write cycle with auto-clear and VCC power up/down write protection eliminate additional timing and protection hardware. DATA Polling and a RDY/BSY pin signal the start and end of the self-timed write cycle. Additionally, the CAT28C17A features hardware write protection. The CAT28C17A is manufactured using Catalyst’s ad- vanced CMOS floating gate technology. It is designed to endure 10,000 program/erase cycles and has a data retention of 10 years. The device is available in JEDEC approved 28-pin DIP and SOIC or 32-pin PLCC pack- ages. BLOCK DIAGRAM ADDR. BUFFER & LATCHES ADDR.
